Sol 10 Sendmail issue
We have a Spark Solaris 10 box running behind a Pix 501 firewall, we are running NAT and I have mapped access to it from the outside world. Anyway, we can receive mail no problem just can't send. I receive this message bounce:
The original message was received at Thu, 10 Jan 2008 17:04:29 -0600 (CST)
from scruffy.oakvalleynet.net [192.168.1.2]
----- The following addresses had permanent fatal errors -----
<richardl@aea16.k12.ia.us>
----- Transcript of session follows -----
550 5.1.2 <richardl@aea16.k12.ia.us>... Host unknown (Name server: mailhost.oakvalleynet.net: host not found)
If I do an NSLookup from the server it can find itself but sendmail doesn't seem to find it.
Have been pulling my hair out for quite some time over this, and and all advice would be much appreciated

GNUNET-NAT-SERVER(1) General Commands Manual GNUNET-NAT-SERVER(1) NAME
gnunet-nat-server - help GNUnet setup test network setup with NAT SYNOPSIS
gnunet-nat-server [options] PORT DESCRIPTION
Normal GNUnet end-users should not concern themselves with gnunet-nat-server. In fact, distributions are encouraged to consider not ship- ping it at all. Running gnunet-nat-server's is similar to running hostlist servers: it is a special service to the community with special requirements and no benefit to those running the service. This program will listen on the specified PORT for incoming requests to test a peer's network connectivity. Incoming requests can ask it to connect to a given IPv4 address (and port) using TCP or UDP and to send a 2-byte test message using the specified address. The program can also be asked to send a "fake" ICMP response message to a given IPv4 address (for autonomous NAT traversal --- see the description in the respective research paper). The idea is that gnunet-nat-server will be run on some trusted hosts with unrestricted connectivity to allow GNUnet users to test their network configuration. As written, the code allows any user on the Internet to cause the gnunet-nat-server to send 2-bytes of arbitrary data to any TCP or UDP port at any address. We believe that this is generally harmless. When running gnunet-nat-server, make sure to use a configuration that disables most NAT options but enables 'enable_nat_client' and sets 'internal_address' to the global IP address of your local host. Also, the gnunet-helper-nat-client should be installed locally and run with root privileges (SUID), otherwise the gnunet-nat-server will not work properly. Note that gnunet-nat-server could be run via gnunet-arm but typically is not. Also, the name of the host and port that gnunet-nat-server is run on should be specified in the NATSERVER option in the [setup] section of the configuration file of hosts that are supposed to auto- configure with this server. OPTIONS
-c FILENAME, --config=FILENAME Use the configuration file FILENAME. BUGS
